Thank you for pointing that out. I've spent quite a while reading the
documentation, but had not realized that. I guess there have been just
too many new things. One thing that probably confused me was the fact
that I first tried out with Stunnel 4.18 in Windows, then changed to
3.26 in Linux. The difference in the usage would have been easier to
notice had the two versions been on the same platform.

I installed the libcurl3-openssl-dev package as suggested and after
that I had no problems installing Stunnel 4.18. I spent Wednesday
learning about certificates and hopefully on Thursday I'll be able
to run some succesful tests.
